After several months of fighting, the eastern, central and southern regions of the empire have been completely occupied. According to the most optimistic estimate of the parliament, the war against the empire will be completely over in two months at most.

At the same time, the railway tracks were built section by section, like a criss-crossing net, covering every major city in the eastern region. In the future, it will be expanded to the entire empire, which also provides convenience for the holding of this academic seminar.

A magic train loaded with passengers left the unfinished platform with a loud whistle and headed towards the royal capital at an extremely fast speed!

The rolling wheels continuously rolled over the rails, making a rumbling sound, and the carriage was also shaking slightly, but the novelty was enough to make people ignore these slight discomforts.

Sean, the middle-aged wizard who had just sat down with his apprentice, saw the dense trees outside the window quickly disappearing from his sight, and couldn't help but sigh. "What an amazing alchemical creation..."

The train they were on was over seventy meters long, could carry nearly a thousand people, and travel at a speed of one hundred kilometers per hour.

It is said that it only takes nine hours to travel from the center of the empire all the way to the capital of the Magic Kingdom!

This also includes the time spent stopping in other cities along the way, which can only be described as incredible.

"Teacher, do you think the night in the royal capital can really be as bright as the day?" The apprentice who was sitting next to Sean and looked no more than eleven or twelve years old couldn't help but ask.

Before, they had been in the empire, but they had heard a lot about the magic kingdom from the passing caravans.

According to the narration of those traveling merchants, the capital was almost like a paradise on earth. Food was made with magic, and even the common people wore exquisite clothes. There were all kinds of novel alchemical creations, and people did not travel by carriage, but by driving a giant steel beast that spewed smoke from the back...

In comparison, the imperial city they were in was simply a cesspool. Even the holy city before its collapse was no exception. Except for the area, everything else was far inferior.

"Of course." Sean explained with a smile, "I heard that it was the masterpiece of Speaker Linn of the Magic Star. It bound the powerful force of thunder in a light bulb and used electricity to create light..."

The young apprentice imagined such a scene, and in a trance, the sky suddenly darkened - the train drove into a long and dark tunnel, and at the speed of this train, it took more than ten seconds before the daylight reappeared.

Such a strong change in light and darkness surprised the wizards in the carriage. Sean, who was leaning against the window, curiously looked through the window and saw a huge mountain behind him!

"It's the Peak of Despair, Dispir!" Sean quickly recognized it. It is the second tallest mountain in the empire, and it got this name because of its steepness.

This train actually went straight through the mountain. No wonder it suddenly felt dark around me.

As Sean watched, he saw a huge tunnel running through the front and back of the mountain, which looked quite spectacular.

He remembered that the kingdom's musketeers had only arrived here three months ago. What kind of power could hollow out an entire mountain in such a short time? Hundreds of wizards in the carriage were also discussing. One of the gorgeously dressed witches said proudly, "The tunnel was created by the Sunfire Cannon, one of the greatest alchemical creations of the current parliament. It only took one shot to blow through the mountain!"

Sean and the others were all in shock. A single strike pierced through the Peak of Despair? What kind of powerful force could be capable of such an outrageous feat?

Many wizards also expressed doubts, believing that this must be hearsay and exaggerated, and that it might have been dug out bit by bit by great wizards using magic.

The witch curled her lips and did not continue speaking. What was a Peak of Despair? The entire holy city was destroyed in the battle between the speakers and the false god.

This Yangyan Cannon was originally intended to be used against the remaining legions of the empire. However, the performances of those nobles were worse than each other, and the battle was over at the first blow. This powerful weapon was of no use at all.

On the contrary, they encountered a lot of trouble when building the road, especially in the central region of the empire, which was full of mountains and steep cliffs. If they had to build the road by taking a detour, it would undoubtedly be time-consuming and laborious.

So Speaker Vittorio suddenly had an idea and used the unused Yangyan cannon to build roads. One shot could cut through mountains and destroy forests. It was so useful!

Sean did not have the slightest doubt about the witch's words, because he had heard that the legendary wizards of the kingdom had used a powerful magic to create a land of death that spread over dozens of kilometers, which was obviously even more exaggerated.

The nine-hour journey was not too far. After the excitement of riding a train for the first time gradually faded away, the train slowly stopped at the platform of the royal capital.

It's already evening!

The witch who had spoken earlier was the first to stand up and walk out of the train, and the others followed.

Sean did not act immediately, but took out his best blue robe from the suitcase and put it on. Then he took a deep breath and stepped out of the train with his assistant and apprentice.

"Welcome to the Magic Kingdom!"

A loud and enthusiastic voice rang in everyone's ears. The person who spoke was naturally Theodore, who was responsible for welcoming the train. He was holding a long list in his hand, confirming each person's name one by one, and then led them to the boarding location.

"This way please gentlemen!"

Sean walked among the crowded crowd, holding his suitcase tightly in one hand. The suitcase contained the results of his life's research, which was also the purpose of attending this academic seminar.

The young apprentice beside him was looking around. Everything in this city was new to him.

He saw the beautifully decorated train platform, the broad, clean and slightly crowded busy streets, the strangely shaped and fast-moving alchemical cars shuttling on the roads, the alchemical workshops emitting thick smoke... Even the bricks and stones of the train platform under his feet were as smooth as mirrors. Stepping on them, he couldn't help but feel guilty for destroying a work of art.

Before the afterglow of the setting sun completely faded, bright rays of light lit up from the tops of the pillars erected on both sides of the street, dispelling the approaching darkness in advance...

Inside the oval lamp is a filament that has been heated to an incandescent color, vividly demonstrating what it means to trap lightning in a light bulb.

In my ears, a soothing song came from nowhere. The melodious tune seemed to contain some special rhythm that made people intoxicated.

"Haha, this is the music played by the wind, a piece of music played by magic!" Theodore explained with a smile.

Since the holy city of the church is filled with loud hymns all day long, the capital of the kingdom, as the face of the parliament, certainly cannot fall behind in this regard! It's nothing strange to say. The so-called sound is the sound waves generated by the vibration of objects. Combined with Dean Lin's resonance principle, as long as a special harp is placed on the statues throughout the kingdom, and a spell is cast to play one of them, the sound will spontaneously resound in every corner of the capital.

And this magic repertoire covering the entire kingdom is naturally the masterpiece of the wave school! As Theodore explained, he led everyone to get on the alchemy cars that had been prepared long ago and head to the Magic Research Institute together.

It was around seven o'clock in the evening when they arrived together.

Sean stepped into the exhibition hall with excitement. It was unexpectedly large, with rows of seats arranged in a circular staircase format. Hundreds of magic lamps overhead illuminated the interior as bright as day. They were obviously the last group to arrive. Tens of thousands of wizards had gathered in the huge exhibition hall, exchanging views and discussing their insights and research in various fields of magic.

However, it was not always so harmonious. Arguments and curses broke out one after another. Fortunately, no one dared to fight in the exhibition hall.

Sean, who was extremely reserved, had no intention of joining the discussion. He sat down with his apprentice at a more outer position, listening attentively to the discussions of the wizards around him.

This year's academic seminar seemed to be particularly grand. It was no longer hosted by great wizards as in the past. Several legendary speakers were all present, which showed how much importance it attached to it.

Sean immediately turned his attention to the Speaker's seat. This was the first time he saw the true faces of several legendary Speakers at the top of magic studies. The figure in the center was particularly conspicuous.

Sean understood that it should be Speaker Linn, the magic star whose reputation spread throughout the empire and made the church tremble with fear.

Just as I was thinking about it, the exceptionally young Speaker looked over, cleared his throat and spoke.

"Everyone, please be quiet!"

An extremely loud voice suddenly resounded throughout the exhibition hall, carrying with it an unquestionable majesty and oppression, instantly bringing the noise and arguments to an abrupt end.

In just one second, the only sound in the huge exhibition hall was the constant echo.

This was Lin En's second time as a judge, so he was naturally very familiar with the various procedures. After briefly saying some polite words and welcoming the many wizards who came from afar, he announced the official start of this magic seminar! Under the gaze of everyone, an old wizard led several apprentices to carry a transparent box and walked into the exhibition hall.

Inside the box is a very sophisticated device. The main body is a huge gear with a diameter of about three meters. Each tooth segment is made into a slope shape. Forty movable short rods are installed inside. At one end of each short rod is a 20-kilogram iron ball, which is moving outward along the spokes of the wheel.

"This is the result of my research, a vacuum gravity perpetual motion machine!" The old wizard who came on stage proudly introduced his great invention to everyone! Nowadays, there are many power devices in the magic world, such as steam engines and improved internal combustion engines, but without exception, they all consume energy.

So he kept thinking, can we find a way to output power continuously without adding any fuel! So this perpetual motion machine was born, which uses the gravity of the planet itself and uses an asymmetric frame structure to make the gravity of the objects on both sides of the frame deviate. The heavy side pulls the light side, producing a repetitive mechanical movement.

In order to eliminate the influence of external forces as much as possible, he also specifically begged a great wizard to drain the elements inside the device so that the device could continue to operate! Looking at this strange perpetual motion machine in front of them, the wizards present were also quite interested.

Although the power output of this thing is limited now, what if it could be magnified a hundred times or even a thousand times?

The power generated might be enough to supply an entire city! Lin En, who was sitting in the judges' seat, rolled his eyes.

Wow, even a perpetual motion machine has come out!

To put it simply, this thing is the same as the Foucault pendulum he used to prove the rotation of planets.

In a vacuum without any interference, Foucault's pendulum can indeed achieve theoretical "perpetual motion" with the help of gravity.

But this perpetual motion machine is obviously still far from perfect, and the biggest problem with this thing is that it simply cannot output much power, and its efficiency is far less than that of using water power, wind power, and solar power.

If this can be considered a perpetual motion machine, then wouldn't a water wheel that runs on water also be a perpetual motion machine?

In just a few words, Lin En pointed out the shortcomings of this "perpetual motion" device one by one.

Sean and the others also noticed at this time that the speed of this perpetual motion machine was gradually slowing down. The great wizards roughly estimated that this thing would stop on its own in two days at most. Obviously, it was still far from the term "perpetual motion".

Vittorio tried to smooth things over, saying that the idea of ​​using planetary gravity to provide a constant source of power was very innovative, but this perpetual motion machine did not have much practical value.

Under everyone's "picking on" him, the originally confident old wizard blushed and kept making excuses, saying that his perpetual motion machine had great potential, but it still needed further improvements. When he finally stepped down, his face was full of indignation. Obviously, he was quite angry that his "great invention" was so unappreciated.

Then Glenn walked up to the stage with his new camera and demonstrated it to everyone. With a burst of flashes, under the effect of magic, a clear black and white photo soon appeared in front of everyone.

This alchemical instrument that can engrave reality onto a "painting" immediately attracted the interest of many people. When it was published in the newspaper before, they were amazed at the lifelike pictures on it. Now, after Glenn's explanation, they finally understood the principle behind it.

"Pinhole imaging? What a great idea..." Aurora said with a smile.

Many people knew about this natural phenomenon, and wizards of the light particle theory regarded it as one of the most direct evidences that light travels in a straight line. However, Glenn was indeed the first person who thought of using this phenomenon.

Lin En and others unanimously gave high praise to this new invention and immediately decided to award him a Morning Star Medal to commend his achievements...
